WorkOS alternatives
The highest-scoring alternative to WorkOS is Permit.io at 79/100 on the AgentReady, against 61/100 for WorkOS.
All scored in Authentication & Identity.
What Permit.io does that WorkOS does not
Permit.io passes clear product positioning, structured api reference, openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented, programmatic credential creation, free trial or free allowance, machine-readable errors, and WorkOS fails them. That is the whole of the gap between the two scores, so if none of those matter to your agent the ranking above overstates the difference.
Why people look for an alternative
WorkOS fails clear product positioning, structured api reference, openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, programmatic credential creation, free trial or free allowance, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
